History+
The founding of Wittichen Monastery in 1324 is attributed to the blessed Luitgard of Wittichen, who, according to tradition, received a divine inspiration to build a house of God there. With 33 fellow sisters, the monastery was established in the secluded area of Wittichen. Initial difficulties, including a fire in 1327, were overcome, and the monastery church was consecrated in 1330. The community received support from the Dukes of Teck, the Counts of Geroldseck, and Queen Agnes of Hungary, which led to papal recognition by John XXII. The monastery acquired extensive property in the Upper Rhine and Neckar regions. After a temporary dissolution during the Reformation in 1540 and significant losses in the Thirty Years' War, the monastery was secularized in 1803 and came into the possession of the House of Fürstenberg. Some of the buildings were demolished in the 1850s due to high costs.
